Microfiber

Tuesday 18 July, 2017

Microfiber or microfibre is synthetic fiber finer than one denier or decitex/thread. This is smaller than the diameter of a strand of silk (which is approximately one denier), which is itself about 1/5 the diameter of a human hair. The most common types of microfibers are made from polyesters, polyamides (e.g., nylon, Kevlar, Nomex, trogamide), or a conjugation of polyester, polyamide, and polypropylene (Prolen). Microfiber is used to make mats, knits, and weaves for apparel, upholstery, industrial filters, and cleaning products. The shape, size, and combinations of synthetic fibers are selected for specific characteristics, including softness, toughness, absorption, water repellency, electrostatics, and filtering capabilities.
Microfiber that is made from petrochemicals includes polyester and nylon which are not biodegradable. However, microfiber made from polypropylene can be recyclable. Microfiber products may also have the potential of entering the oceanic water supply and food chain similar to other microplastics. Synthetic clothing made of microfibers that are washed can release materials and travel to local wastewater treatment plants, contributing to plastic pollution in water.
Microfiber fabric is often used for athletic wear, such as cycling jerseys, because the microfiber material wicks moisture (perspiration) away from the body, keeping the wearer cool and dry. Microfiber is also very elastic, making it suitable for undergarments. However, the US Marine Corps banned synthetic fabrics for wear with uniforms while deployed to combat environments in 2006, because of instances where Marines' undergarments were melting under extreme heat caused by IED (improvised explosive device) blasts, causing more damage to the skin. They released a "fit for duty" version authorized earlier that same year.
Microfiber can be used to make tough, very soft-to-the-touch materials for general clothing use, often used in skirts and jackets. Microfiber fabric can also be used for making bathrobes, jackets, swim trunks, and other clothing that can be worn for aquatic activities such as swimming. Microfiber can be made into Ultrasuede, an animal-free imitation suede leather-like product that is cheaper and easier to clean and sew than natural suede leather.
